To Ernst Dieffenbach 9 February [1847]
Summary
On the results of Robert Bunsen’s journey to Iceland, which he compares in detail with his own research.
"I have for the present given up Geology, & am hard at work at pure Zoology & am dissecting various genera of cirripedes, & am extremely interested in the subject." "I always, however, keep on reading & observing on my favourite work on Variation or on Species, & shall in a year’s time or so, commence & get my notes in order."

To Ernst Dieffenbach 4 July [1843]
Summary
CD gratified that ED wants to translate his Journal. Will send a copy of Coral reefs, which contains a fuller treatment of topic. Perhaps ED would insert a note to this effect. Can lend woodcuts from Coral reefs if ED wants. CD will send a few corrections; he wants to amend way he criticised Agassiz’s glacier theory.
He is also enclosing a questionnaire concerning differences between races or varieties and species, about which he intends to publish sometime.

To Ernst Dieffenbach 2 October 1843
Summary
On ED’s planned edition [German] of CD’s Journal of researches.
Informs him of his forthcoming volume, Volcanic islands.
"I am well acquainted with your paper on Chatham Island ["An account of the Chatham Islands", J. R. Geogr. Soc. 11: 195–215], & … those passages on the very curious fact of the apparent specific differences of the birds there & at New Zealand".
Thanks ED for recognition of his "small labours in Natural History… . praise from men, like yourself, is the only, though quite sufficient, reward I ever expect or wish to obtain for my works. – I have lately had the extreme satisfaction of hearing that Hooker speaks highly of the accuracy … of my statements". Refers to Humboldt and Owen.

To Ernst Dieffenbach 16 December 1843
Summary
"You will have been sorry to have seen in the newspapers, the disturbances & fightings with the New Zealanders. – I have lately been much interested in reading your chapters on the slow decrease in numbers … of these poor people. The case appears to me very curious, especially as the decrease has commenced or continued since the introduction of the potato – the relation between the amount of population & of food is hence inverted. It would have been a case for the great Malthus to have reflected on".

To Ernst Dieffenbach [before 9 July 1845]
Summary
"It is evident that you have not time now to pay me a visit, & indeed as Mrs Darwin is in daily expectation of her confinement I could hardly have asked you … When I saw your name & that of many other naturalists at Cambridge, I wished much to have been there; but my strength so often fails me, that I expected more mortification than pleasure …
I should have liked to have heard the Crater-of-Elevation discussion; after having read both sides, I cannot subscribe to that view; but I think there remains something unexplained about those many vast circular volcanic ruins …
I presume it is very unprobable [sic] that there will ever be a second German Edition of my Journal … I have largely condensed, corrected & added to the Second English Edition, & I am sure have considerably improved & popularised it".

On geological works of Tschudi and Buch.
"My health keeps indifferent & I do not suppose I shall ever be a strong man again: everything fatigues me, & I can work but little at my writing: this summer, however, I shall get out my geology of S. America".
"I found Bronn’s Geschichte, which you recommended me, very useful, for references to facts on variation".
